That sounds too good to be true. Is this just a scam?
First let me tell you that Reverse Phone Detective DEFINITELY isn't a scam.
Have you ever needed to find someone and all you had to go on was a phone number? Perhaps you are getting prank phone calls at all hours of the night. Maybe someone you know is involved in suspicious activity and you know nothing about it other than the phone number they've been calling.
What can you do about it?
You could go through the phone book, page by page, checking to see if the number in question is listed. That might take a few years. And what if the number in question is unlisted? Then it isn't in the book at all! What can you do in that case?
You can use Reverse Phone Detective. They can find the name and address for just about anyone, including those for cell phones.
